the invention being, herein explained and the best mode in which I have contemplated applying that prinf'ziple. so as to distinguish it from other inventions. I

My invention has more particular reference to the application of a heating element to some feasible type of suction device and i .ali'ned across and adjacent to the periphery specifically adjacent the niout-h or intake opening thereof. 1

It is common inthe printing art to pass a freshly printed she'et'tlirough a heated zone .never been combined ivithfasi in order to prevent offset. So far 'asl am a\\"are, however, thisprev-entive agency has' lion device from the eon. with purposed trr remove'loose part plishin'ent of one of the results sought:

.(fonsonantly my object has been to make possible thecooperation of a suction effect such that the movin; sheet is compelled to travel not only through a heated zone but in definitely prescribed proximity to the source of heat. l

My iiu'enti'on'inot only dries the. sheet but neutralizes or abstracts its static electricity. I would have it expressly understood that I in no wise limit myself to this specific application or embodiment of my invention, which I-l|a\'e. selected as'a bas s for illus trating and describingmy invention merely. for; the purpose of, rendering a clear; and comprehensive umlerstandine of the scope and novcl features thereof.

Adverting to the drawings: lfi gure I is a hdiailframiriatic plan view sho\\"ing the application of my invention to the cylinder of a printing press. Fig. II'is an enlarged see-- Fig. III is'a similarly enlarged end view looking into the mouth of the nozzle as suggested by line BB on Fig. II. Fig. IV is a still further enlarged section of the heating element.

The cylinder of the printing press in association with which I baveelected to illustrate' my invention is designated with the reference numeral 1.

At same suitable location is a suction to be explained.

supported form which should be presumed as in most-e1 SUCTION-NOZZLE HEATER FOB; PRINTING-PRESSES.

motor 2 which is operatively connected with 'a lleiv ible header duct 3 and this in turn with a manifold 4 having a pluralitv (eight) of branches 5. The branches 5 are cou led t (i with a corresponding number of constricted outlets of a nozzle structure 7 whichniay' be either. of integral manufactni'e or comprise a similar number (if-flared I nozzles suitably secured together. The

The adjustability is primarily'to allow for expansion and; contraction. of the heating element. In tbiiorm shown there are two heating elements 11. "extending the entire. lengthof the combined intake openings 8 and located just above and below the' same is seen in both Figs.

entitled Suction nozzle for pre ses liled ofeven date herewith and bearing Serial .\'o 26,368. The heatingelenients ll quite arbitrarily are made to functionate through thefageney of electricity 4 supplied to an interior coil 12 disposed in packing 15; and insulated by air chambers 14 in all directions'wi'th the exception of one which is opposed to the periphery of the cylinder'l. In such direction the-heating element presents 'a mica sheetlfi and pro tccting cover 16 whereby the heat is radiated almost exclusively tllCX'CtlH'OIIQlI. and thus intensified and made more effective for the purposesof my present invention. The

cover 16 is additionally fashioned with diagonal grooves 17 which are clearly seenin Fig. III. The purpose of such grooves is tomake possible the employment of a very strong suction effect without warping or otherwise 'disarranging the sheet during its travel past the intake of the nozzle.

My invention obviates the necessity of drying the ink ona printed sheetelsewhere with some special heat supplying agency. It also neutralizes or sufficiently abstracts the electricity which manifests itself in all paper a stock thereby presenting. the same in better condition to the type form.

I claim;

1. An appliance of the character described, comprising in combination with a sheet conveyer, a suction nozzle opposed thereto, means for establishing a suction effect through said nozzle, and a heating surface contiguous to the edge of the nozzle conveyer and spaced from the latter, said member having the major portion of its exterior surface insulated to leave a long narrow radiating surface, the latter being opposed to said conveyor.

4. An appliance of the character described, comprising in combination with a sheet conveyer, a suction nozzle having a long narrow intake opening opposed to said conveyer, means for creating a suction in said nozzle, and a pair of heating elements .carried by said nozzle and extending along opposite sides of said intake opening.

An appliance of the character de scribed, comprising in combination with a sheet conveyer, a plurality of suction nozzlcs having mouths opposed thereto, a inanifold connecting the outlets of said nozzles, suction means in communication with said manifold, and a heating member extending along all of saidnozzle mouths and between thesame and said conveyer,

6. A suction nozzle comprising a hollow member and a heating element carried thereby adjacent the intake opening thereof.

7. A suction nozzle comprising a hollow member having a long narrow intakeopening adapted to be opposed to a given surface with a relative movement between said mem: her and surface,'and a heating element secured to and extending along one side of said opening whereby not to obstruct the latter.--

8; A suction appliance comprising a plurality of nozzles having alined openings, a manifold connected with said nozzles, and a heater connecting and extending adjacent said openings.

9. An appliance of the character described, comprising the con'ibination of a sheet conveyer on which a sheet is adapted.

to travel, a suction nozzle having its mouth opposed to said conveyer, means for establishing a suction effect in said nozzle, and a heater mounted adjacent said nozzle intake and having that surface which is opposed to said convcyer fashioned with diagonal grooves. I

10. An appliance of the character described, comprising the combination of a sheet conveyer, a suction nozzle having an,

intake opening opposed thereto, means for establishing a suction effect through said nozzle, and a heating device mounted adjacent said nozzleamhalong said opening.

11. An appliance of the character described, comprising the combination ofa sheet conveyer, a suction nozzle opposed thereto, and means for establishing a heated zone about the mouth of said nozzle.

12. An appliance of the character described, comprisinga sheet conveyer, suction nozzles having alined intake openings opposed thereto, means for establishing a uniform suction through said nozzles, a structure forming a continuous slot across said nozzle openings, and means for heating said structure, adjacent such slot.

13. An appliance of the character described, comprising a sheet conveyer, suction nozzles having alined intake openings op posed thereto, means for establishing a uniform suction through said nozzles, and

a heating member for joining said nozzle openings into a common continuous intake slot extending across the width of the passing sheet whereby to insure a uniform appli-.

cation of the suction effect.
